Charlie,
At present we do not belong to BBB. They could be a big help in some communities. They are looked upon by older people as the Bible of Good Contractors. Unfortunately this is not true. The BBB is a group that offers membership and holds their members to a standard. Pretty much like any good org. would do. They even take responses from people who take the time to evaluate a business. I actually reported a local business using our PDCA logo and not a member. They kicked them out of BBB, but they still promote the PDCA without membership! Not all BBB businesses are good. If your clientel is older, I'd join. If they are younger, check it out with them. Ask if they ever refer to the BBB. Thank you.
